ＶｏＱ１６−＆ １０ （Ｏｃｔ１９６５）に詳しく述
べられている。Adhesive growth of aquatic organisms in the cooling seawater system is called deposits, 1
1) If they fall off and flow, they may cause blockage or abnormal damage to the heat exchanger tubes, abnormal clogging of the strainer, or a decrease in I/II water volume, resulting in a decrease in plant efficiency and operational problems. There is also the risk of causing problems. Injecting chlorine into water supply channels has traditionally been a method of preventing the adhesion of marine organisms. These techniques are described in detail in Thermal Power Generation VoQ16-&10 (Oct. 1965) published by Thermal Power and Nuclear Power Generation Technology Association.
ところで、給水中への塩素の注入方法としては。By the way, how do you inject chlorine into water supply?
塩素を封入した高圧容器から直接給水中に塩素を投入す

。これに対する１つの試みとして、特開昭５３−８５５
５１号では。However, in the method of directly charging chlorine from a high-pressure container, transporting and handling the high-pressure container is dangerous, and the chlorine is
Large-capacity water supply systems such as power plants (1 plant has 300
,000 tons/11)), the wastewater seawater may have a negative impact on the marine ecosystem, so the injection of chlorine tends to be avoided due to environmental conservation concerns. For the above-mentioned reasons, there is a strong demand for a method for preventing the adhesion of marine organisms after chlorine injection. As an attempt to solve this problem, Japanese Patent Application Laid-Open No. 53-855
In issue 51.

気に放出するなどの処置が必要であった。It has been proposed to prevent marine organisms from adhering to heat exchangers by periodically replacing water in the cooling water system with ozone-containing gas. However, when draining water from the cooling water system, it is replaced with ozone-containing gas, which requires complicated switching operations such as stopping the water supply to the system and limiting the load on the plant. It was necessary to decompose unreacted ozone through a decomposition device to eliminate any toxicity before releasing it into the atmosphere.

を防止することが出来る。As mentioned above, the conventional method of preventing marine organisms from adhering to the water supply system, which involved injecting sterilizing products, had many problems, but there is an alternative method that does not have an impact on the environment and is simple. One method that is highly effective in preventing biofouling is the method of irradiating with ultraviolet light. This method utilizes the sterilizing effect of ultraviolet light with a wavelength of 253.7 m2, and irradiates ultraviolet light onto environmental areas where marine organisms tend to attach and grow, such as the walls of water supply systems, ice chamber walls of heat exchangers, etc. can prevent the adhesion of aquatic organisms.

There was a problem that impurities such as dirt and dust inside the tube would adhere, and the illuminance of ultraviolet rays would drop significantly, resulting in a loss of the biofouling prevention effect on the walls of the water channel and the walls of the heat exchange chamber. In experiments conducted in flowing seawater from May to August, mud as described above,
Due to the adhesion of dust, etc., the illuminance has decreased to about 3% of the initial level for 3 months.
